I was joined by Christopher Walker from Have a Drink, Mike Stuart from MadTree and Greg Avola from Untappd to explore how the Untappd app has changed the act of drinking beer for so many people in the world. What is it? Where is it going? We have so many questions to throw at Greg and he fields them all. In addition we pestered the Brew Professor himself about MadTree and this mysterious Sensorium Series that they've been hinting at. We get the lowdown on that, plus so much more! Big Thanks to Chris, and everyone from the Have a Drink Show for helping with this episode!
